Abstract: The development of knockout or knockdown mice, showing a depressive or depression-resistant phenotype, have allowed us to better understand the complex relationship between genes, behavior and acquired disposition in mood disorders. Preclinical and clinical studies have established that a dysfunction of serotonin (5-HT) neurotransmission is a common hallmark in depression. Genetic mice models with a gene manipulation of?transporter, receptor, protein, enzyme gene in 5-HT system show depressive or depression-resistant phenotype. The present review revises ten genetically engineered mice models with mood alteration (either includes 5 genotypes) and summarizes their each physiological fuction,molecular mechanism, behavioristics,neurophysiology and even those translated to human. In turn, findings from human studies have helped to design and generate genetic mice models to explore new hypothesis of the etiology of human depression, and most important, to explore and refine new strategies for antidepressant medication.
